To all whom it may concern:

Be it known that I, FRANK A. WHITE, a citizen of the United States residing at Cleveland, in the county of duyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Dispensing Ice-Cream, of which the followin is a. specificatiom his inventionrelates to" a machine for dispensing ice cream and it has for 1ts object to provide a machine which wlll cut the cream in thedesired form, insert 1t wlthln a container formed of dough similar tothat 1 and 3: Fig. 3 is a horizontal section on the line 3-3 of 1; 4,-5 6am detail sections corresponding to the hnes 4,

5and6of-Fig. 3. r V Describing the parts by reference numerals: 1 represents an ice chest of suitable con struction and provided with compartments 2, 3 and 4. The compartment 2 opens at the front of the chest through a swlng door 5 and provides a means for storing and con'-. .taining the bricks of ice cream. The compartment 3 surrounds the compartment 2 and acts to contain the refrigerating med um, while the compartment 4 is merely "a convenient place for storingsurplus containers'. p

Located within the compartment 2 is a chute 6 which extends from the bottom thereof substantially to the top, and-said chute has slidably mounted therein a shelf 7 which has a connection 50 with an endless chain 8 mounted upon sprocket wheels 9 and 10 and located in the rear of said chute, the sprocket 9 being driven. and by means to be hereinafter described causes the shelf 7 to rise, carrying with it a brick of ice cream 11 previously placed thereon. The sprocket 9 is mounted upon a horizontal shaft 12 suitably supported in bea formed as part of the housing 13 which sep-' arates the refrigerant from the operating parts and said shaft has fixed to its end a bevel gear 14 which meshes with a like gear 15 secured upon a transverse shaft 16, supported upon the chute and projecting through'the front of the chest 1 where it has secured toit a ratchet wheel 17, said ratchet tent movement through a pawl 18 carried upon an arm 19 supported upon its end upon the shaft 16 and having its opposite-end pivotally secured through a link 20 to a crank 21 fixed against rotation upon a main operating shaft 22 hereinafter described. A detent pawl 23 prevents the ratchet 17 from allowing any backward movement of the shaft 16 when a brick of ice cream is upon the shelf, and this detentmay be manually freed from the ratchet when it is desired to retrieve'the parts in such a manner as to allow the insertion of a new brick cream upon the shelf 7.

As viewed in Fig. 1 at the leftof the chest is mechanism for storing and feeding the containers, one at a time, to the proper location for receiving the ice. cream and of ice which consists-of an elevating means similar to that employed for lifting the .cream, the parts which are identical bearin like reference numerals with the added s a. The driving shaft 12', suitably supported, has fixed thereon the sprocket 9 to which the elevator chain is attached and to that end which projects through the chest 1 has affixed a gear 24 and saidshaft is prevented from any reverse movement by a pressed pawl 25 which engages the teeth of the gear 24. This gear is intermittently rotated by a ar se ent 26, secured upon a stub shaft 27, having fixed thereon a crank 28 provided with-an operating handle 28 also secured to said stub shaft 27 is a secon crank 29 provided at its end with an antifriction roller 30 which, upon each rotation of the shaft 27 engages a camarm 31 fixed upon a shaft 32 supported in bearings tened to the side of the chest 1 and this shaft has 'aflixed intermediate of its bearings a leverarm 33v which has its opposite end projecting through a slot in the arm 34 of a pusher-head'35, said head being allowed wheel being adapted to be given an intermithas to reciprocate in a horizontal direction be- 'of which are guided between the side walls v40 of the housing 39. The plate 37. has secured to its upper face a standard 38 which is allowed to operate through-slots in the plate'41 and has-fixed to its upper end the squared shaft 22, which extends through a sleeve 22 and within a suitable bearing 90 to the outside of the chest 1, where it has secured to its end the operating handle 22. The sleeve 22 allows the shaft to rotate within the bearingto operate the elevator mechanism. I The crank 21 is rigidly secured to the, rotatable sleeve 22", which sleeve is rotated through the squared shaft 22 and handle 22. The interior of the/sleeve 22 is squared so as toaccommodate the shaft 22, yet the fit is loose enough to permit longitudinal sliding movement of the shaft 22 in the sleeve. The cutting blade is formed by the plate 37 being provided at its forward end with a squared opening 43 which is equivalent to the cross dimension of the brick of cream, the forward side or edge of the. opening being sharpened to provide a cutting edge 44, when the blade is forced rearwardly by the operator pushing the shaft 22 a slice of cream is severed from the brick and is then forced into' the container by a pusher. 42, which is formed by the upturned forward end of the plate 41. This plate is normally held in a rearward position by two tension springs 46 and is prevented from too quick a return by a pneumatic cushion formed by a iston reciprocating within a c linder 4 The forward movement of this pusher is obtained by a trigger 48 carried by the shaft 22 which falls by gravity when the arm 49 of the trigger leaves the top of the bearing 90, when the shaft 22 is moved rearwardlyand whose portion 50 rides over the top of the head 51 of the pusher and then falls to the rear of the head. As the shaft is drawn forward it carries the pusher with it until the arm 49 of the trigger rides over the bearing- 90 and releases the pusher, which returns to its normal position through the action of the springs 46.

After the container has been filled it rests upon a shelf 54 which is pivoted upon a shaft 55 secured to the housin said shelf com-' prising in effect a trap 55 and is opened at the proper time by a release which consists of a trigger-57, having one of its ends secured to the side of the plate 41 -and.its other end provided with a catch 58 which engages the arm of a bell crank 59 ,pivotally secured to the housing oor which is nor- 7 mallyheldclosed or in a horizontal posi tion by a torsion spring 56 about the shaftand the other arm of the hell crank engages the upper face of the shelf and when 'the pusher mechanism returns causes the shelf to swing about its pivot, allowing the finished product to fall through an opening 60 in the front of the chest 1' and lodge in a cup 61 fastened thereto.

The container comprises a hollow cake substantiallysq'uare and about one inch in thickness. This cake is closed on all sides but'one, which when presented to the slice of cream allows the same to be pushed within, presenting to the consumer a product similar. to the sandwich nowo on the market, but providing against the cream squeezing out at the edges when the sandwich is bitten into.

In operation, the containers are first advanced by operation of the head 35 until the first container is in line with the pusher 42. The handle 22*, shaft 22 and sleeve 22 are then turned to lift the brick 11 in position to cut off a slice. The shaft 22 is then pushed in, advancing the cutting edge 44 and cutting ofl" a slice. The shaft 22 is then pulled out to full extent and the pusher 42 (being then engaged by the trigger 48) iS advanced and pushes the slice into the container. The pusher is then returned by the springs 46, to original position, and the crank 59 is then operated by the catch 58 to open tlflfi trap door 54 and drop the container rough the delivery-spout 60.

I claim:

1. In a dispensing machine the eombina tion of an upright chute adapted to hold a body of material, a lifting mechanism in said'chute adapted to lift said bodyto extend a portion thereof beyond the chute, a

magazine for containers'located beside the 1 .chut, means to lift the containers in the magazine to position successively beside the top of the chute, a cutting mechanism working transversely across the top of the chute and adapted to sever a portion of the said body of material, means to advance the portion so severed into the adjacent container, and means to dischargethe filled container from the machine.

2. Inan ice-cream dispensing mechanism the combination of a magazine'for holding bricks of cream, a re gerating chamber about said magazine, a elevating device working in said magazine and adapted to lift the block through an opening in the top of the magazine, to expose a portion of said block, a cutting blade movable across said opening in the ma zine and adapted to sever the exposed portion of the brick,

portion into the foremost container, and
